To me, the interesting angle on this device is that the C/C++ toolchain is all web based, so there's no software installation required to get started. (I had a similar idea some time ago for another embedded board, but couldn't convince the company to try it out.) Seems like the zero installation toolchain would make it easier for people to get started, especially if they are on a locked down OS.
I also like their idea of having the board appear as a USB drive with FAT filesystem; copy the new firmware over and it will automatically reflash the microcontroller.
